please don't use bleach, that is dangerous not only to your health but the enviroments. if you are not concerned about area plants (ie. sidewalk crack weeds) you can pour boiling vinegar water on the weeds. if you are concerned about surrounding plants carefully pour directly onto the plant saturating with just plain boiling water or spray to saturation directly on "weed" vinegar eps. best on a sunny day to help dry out the plants. you may have to redo treatments, but it's worth it imo since it's safe and mostly effective.
Ahhh tea the essence of life.
